1WORX20% OffWORX WG737E 40V PowerShare Brushless Cordless Lawnmower 37cm
Main highlights- Lawn mower dimension: 117(L) x 42 (W) x 106.5 (H) cm; Cutting height range: 20 - 70 mm
- COVERS UP TO 550M² WITH DUAL 20V 4.0AH POWERSHARE PRO BATTERIES – Two WORX NITRO 20V 4.0Ah PowerShare PRO batteries deliver combined 40V power for uninterrupted mowing of gardens up to 550m². Both batteries are fully compatible with the entire WORX PowerShare platform, sharing charge across 20V, 40V, and 80V tools for maximum value. A charger is included, and the cordless design eliminates cables and fuel — making every mowing session cleaner, quieter, and more convenient than petrol alternatives.
- ADJUSTABLE CUTTING HEIGHT & WORX POWERSHARE COMPATIBLE – Multiple cutting height settings allow fast, tool-free adjustment to suit different grass lengths and seasonal conditions throughout the year — from a short formal cut to a longer, more resilient height during drier periods. As part of the WORX PowerShare ecosystem, the WG737E shares batteries and chargers with the complete range of WORX 20V, 40V, and 80V tools, making it a cost-effective and versatile addition to any existing WORX collection.
- 40V BRUSHLESS MOTOR WITH INTELLICUT FOR POWERFUL, ADAPTIVE MOWING – Powered by a robust WORX NITRO brushless motor with smart IntelliCut technology, the WG737E automatically adjusts cutting power to match grass thickness in real time — conserving battery on lighter growth and increasing torque through denser, tougher grass. The result is a consistently even, precise cut across every lawn condition, with longer runtime, quieter operation, and a significantly extended motor lifespan versus brushed alternatives.
- 37CM CUTTING DECK — COMPACT, LIGHTWEIGHT & EASY TO MANOEUVRE – The 37cm cutting deck is ideally sized for medium gardens and narrow or sloped areas where wider mowers struggle to manoeuvre. At just 15.3kg, the WG737E is lightweight enough to lift, carry, and navigate around obstacles with ease — making the mowing experience manageable for the whole household. The compact design also simplifies storage in smaller garages and sheds when the mowing season is over.
- 2-in-1 Bag & Mulch Functionality - The WG737E lawn mower comes with a 2-in-1 bag and mulch functionality. You can easily switch between the mulch plug and grass bag according to your lawn care needs. The bagging collection rate is up to 90%, saving you significant effort on bagging and dumping. The mulching feature returns nutrients back to the soil, promoting a healthier and greener lawn. This versatile functionality makes the WG737E lawn mower a game-changer in fast and efficient lawn care.
